Morphology and infraciliature of three species of Metaurostylopsis (Ciliophora, Stichotrichia): M. songi n. sp., M. salina n. sp., and M. marina (Kahl 1932) from sediments, saline ponds, and coastal waters

Two new urostylid ciliates, Metaurostylopsis songi n. sp. and Metaurostylopsis salina n. sp. and Metaurostylopsis marina (Kahl 1932) are investigated using live observation and protargol impregnation. These species were isolated in Korea from intertidal sediments, saline ponds, and coastal waters. Metaurostylopsis songi is in vivo about 120 microm x 25 microm, has a slenderly ellipsoidal body, colorless cortical granules in rows on ventral and dorsal body sides, about 54 macronuclear nodules, 28-47 adoral membranelles, five frontal, two or three frontoterminal and six or seven transverse cirri, and 9-12 midventral cirral pairs followed posteriorly by 1-3 single cirri. In vivo M. salina is about 60 microm x 25 microm, has a pyriform body, colorless cortical granules irregularly arranged, about 45 macronuclear nodules, 18-23 adoral membranelles, three frontal, three to five frontoterminal and two to five transverse cirri, and four or five midventral cirral pairs followed posteriorly by five to seven single cirri. Both species have three marginal cirral rows on each body side and 3 long dorsal kineties. The Korean specimens of M. marina match the Chinese population in all main features. Metaurostylopsis songi differs from M. marina by the more slender body, the number of frontal cirri (invariably five vs. four), and the arrangement of cortical granules (in rows on dorsal and ventral cortex vs. only along dorsal kineties and anterior body margin). Metaurostylopsis salina differs from its congeners by the distinctly smaller size, the pyriform body shape, the scattered cortical granules (vs. in rows), and number of frontal cirri. It differs from M. marina also by the number of midventral cirral pairs (four or five vs. seven to 11).

中国甘蔗亚族几个容易混淆物种的订正

通过标本研究和野外考察发现:被鉴定为二色金茅和滇南金茅的国产标本实际均为四脉金茅,且二色金茅和滇南金茅在国内无分布,国内各植物志中该名称下的类群应归入四脉金茅。另发表一新组合E. quadrinervis var. latifolia(Rendle)Y. C. Liu & H. Peng.; 国内各植物志和各大标本馆在描述和鉴定Microstegium ciliatum时,常与M. fasciculatum混淆,并在各种场合错误引证; 在此澄清二者真正的区别。     

On Soil Rotatoria from a Lithotelma near Halali Lodge in Etosha National Park in N-Namibia,South Africa

A soil sample out of a dried rockpool (lithotelma) on a dolomit hill in the Etosha National Park, Namibia, was investigated for possible occurence of rotifers. Besides a numerous and rich microfaunae, e.g. Zooflagellata, Rhizopoda. Acari, Nematoda, Tardigrada and Copepoda, 24 rotifers were found. Until today, four so far unknown Bdelloidea could be described: Dissotrocha decembullata n. sp., Dissotrocha hertzogi aculeata n. ssp., Otostephanos jersabeki n. sp. and Philodina foissneri n. sp.     

Description of Dolichodorus grandaspicatus n. sp. (Nematoda: Dolichodoridae)

Dolichodorus grandaspicatus n. sp., collected from soil about roots of a red maple (Acer rubrum L.) in a creek bottom near Ludwig. Johnson County, Arkansas, is described. It differs from two closely related species, D. marylandicus and D. heterocephalus, by the longer spike on the female tail, the lenght of the female tail, and the shape of the extrudable portion of the gubernaculum of the males. It further differs from D. marylandicus by having heavily sclerotized accessory pieces of the vuvla and from D. heterocephalus by having a shorter stylet.     

Endonura Cassagnau in Iran,with a key to species of the genus (Collembola,Neanuridae, Neanurinae)

Three new species of Endonura are described from Iran. Endonura dichaeta sp. n. can be recognized by an ogival labrum, head without chaetae O and E, chaeta D connected with tubercle Cl, tubercle Dl with five chaetae on head, absence of tubercles Di on thorax I and tubercle (Di+Di) of thorax V with 2+2 chaetae. Endonura ceratolabralis sp. n. is characterized by large body size, reduction of labral chaetotaxy, ogival labrum, head without chaeta O and fusion of tubercles Di and De on first thoracic segment. Endonura persica sp. n. is distinguished from its congeners by a nonogival labrum, absence of chaeta O, tubercles Dl and (L+So) with five and eight chaetae respectively and claw with inner tooth. The key to all species of the genus is given.

Description of Quinisulcius solani n.sp. (Nematoda: Tylenchorhynchidae) with a Key to the Species and Data on Scutylenchus koreanus from Pakistan

A new species. Quinisulcius solani, is described and illustrated from specimens on Solanum tuberosum from Murree Hills, Pakistan. Q. solani n.sp. differs from its closest relative, Q. acutus (Allen, 1955) Siddiqi, 1971, by its spiral to open ''C'' shaped body and stylet length of 19 μn, vs. 17 μm in Q. acutus. In Q. acutus the stylet knobs project anteriorly but slope posteriorly in Q. solani n.sp. Tail annules number 17 in Q. acutus but 38 in Q. solani n.sp.; also the phasmids in the former species are at mid-tail and in the latter are in anterior half of tail, at about 34%. Q. solani n.sp. is also closely related to Q. capitatus (Allen, 1955) Siddiqi, 1971 but differs in some characters. Head annules number eight and stylet length is 17 μm in Q. capitatus, but head annules are six and stylet length is 19 μm in Q. solani n.sp. In Q. capitatus T/ABW is 3 vs. 2.2 in Q. solani n.sp. Also, phasmids are located at mid-tail on Q. capitatus but at ahout one-third of the tail on Q. solani n.sp. A key to the 10 species of Quinisulcius is also presented. Scutylenchus koreanus (Choi &Geraert, 1971) Siddiqi, 1979 is recorded for the first time in Pakistan and morphometric data and illustrations given.     

Meloidogyne aquatilis n. sp (Nematoda:Meloidogynidae) from Spartina pectinata with a Key to the Canadian Species of Meloidogyne

A new root-knot nematode, Meloidogyne aquatilis n. sp., attacking the roots of Spartina pectinata Link growing in the Ottawa River is described and illustrated. Meloidogyne aquatilis is distinguished from M. graminis by the light brown body color and by the absence of perineal lateral fields in the female. The male differs by the shorter stylet and by the hemizonid being separated by 7-9 annules from the excretory pore. The second-stage juveniles are also recognized by the 7-9-annule gap between the hemizonid and excretory pore and by the shorter tail with a disc-like subterminal tail structure, lower b ratio value, and inflated rectum. A key to the root-knot nematode species of Canada based on females, males, and juveniles is provided. The type host of Dolichodera fluvialis Mulvey and Ebsary, 1980, Spartina pectinata Link, is reported for the first time.
